Goals / Objectives
1) To obtain unbiased, valid comparisons between new and standard cultivars and promising selections from the UF/IFAS strawberry breeding program, using standard cultural and pest management practices. Variables to be measured include plant size, disease resistance, earliness of production, productivity, pedicel length, fruit weight, and components of fruit quality (including color, shape, firmness, soluble solids, titratable acidity, and antioxidant levels). 2) To determine the influence of propagation site, planting date, plant spacing, fertilizer rate, and watering regime, as well as other potential cultural and pest management practices, on the performance of standard cultivars, new cultivars, and promising selections.
Project Methods
Replicated trials will be used for the evaluation of most traits and management practices. These trials will usually consist of four to six replications of each genotype and treatment, arranged in a randomized complete block design. Spreader rows will be used in disease screening trials to aid in the uniform spread of inoculum. Plots will typically consist of 10-16 plants. Standard cultivars will be included in all trials for comparison with new cultivars and advanced selections. Non-replicated blocks of plants may be used to obtain fruit for sensory and post-harvest evaluations.

Progress 01/01/03 to 12/31/07

Outputs
OUTPUTS: A strawberry variety trial was conducted each year from 2003 to 2007 at the Gulf Coast Research and Education Center at Dover (2003-05) and GCREC-Balm (2006-07). In these trials, the performance of advanced selections from the UF/IFAS strawberry breeding program were compared to new and standard varieties. Results from these trials were reported at field days, grower meetings, and in three U.S. plant patent applications. PARTICIPANTS: Not relevant to this project. TARGET AUDIENCES: Not relevant to this project. PROJECT MODIFICATIONS: Not relevant to this project.

Impacts
Information generated from this project helped growers determine which strawberry varieties were best for west central Florida, in terms of fruit yield and quality. Information from these trials was also used in U.S. plant patent applications for 'Winter Dawn' (2005), and 'Florida Radiance' and 'Florida Elyana' (2008). 'Winter Dawn' has become an established early variety in Florida and Egypt, while 'Florida Radiance' is showing promise in Florida and Spain. 'Florida Elyana' is relatively low yielding, but has exceptional fruit quality so we expect it to be grown for certain high-end markets around the world.

Progress 10/01/06 to 09/30/07

Outputs
The following 12 entries were evaluated at the University of Florida Gulf Coast Research and Education Center (Balm) during the 2006-2007 strawberry fruiting season: Festival, Treasure, Carmine, Winter Dawn, Sweet Charlie, Rubygem, Albion, Sugarbaby, FL 99-117, FL 99-164, FL 00-51, and FL 01-116. Sweet Charlie produced the highest December yield (129 g/plant), followed by FL 01-116 (112 g/plant), Rubygem and Carmine(109 g/plant), and Festival (105 g/plant). Festival produced the highest early season (December through February) yields (464 g/plant), followed by Winter Dawn (421 g/plant), Carmine (391 g/plant), and Sweet Charlie (386 g/plant). Festival also produced the highest total season yield (1005 g/plant), followed by Carmine (835 g/plant), Winter Dawn (777 g/plant), Sweet Charlie (738 g/plant), and FL 99-164 (730 g/plant).

Impacts
The 2006-07 GCREC strawberry variety trial provides growers in central Florida the information they need to choose the highest yielding early season cultivars.

Progress 10/01/05 to 09/30/06

Outputs
The following seven entries were evaluated at the University of Florida Gulf Coast Research and Education Center (Balm) during the 2005-2006 strawberry fruiting season: Festival, Carmine, FL 95-269, FL 99-117, FL 99-164, FL 00-51, and FL 01-116. Carmine produced the highest December yield (88 g/plant), followed by Festival (61 g/plant), FL 01-116 (52 g/plant), FL 00-51 (38 g/plant), FL 95-269 (26 g/plant), FL 99-164 (26 g/plant), and FL 99-117 (18 g/plant). Carmine and Festival also had the highest total (December through February) yields (407 and 261 g/plant respectively), followed by FL 99-164 (222 g/plant), FL 95-269 (217 g/plant), FL 01-116 (206 g/plant), FL 00-51 (197 g/plant), and FL 99-117 (151 g/plant).

Impacts
The 2005-06 GCREC strawberry variety trial provides growers in central Florida the information they need to choose the highest yielding early season cultivars.

Progress 10/01/04 to 09/30/05

Outputs
The following seven entries were evaluated at the University of Florida Gulf Coast Research and Education Center at Dover during the 2004-2005 strawberry fruiting season: Sweet Charlie and Winter Dawn (FL 97-39) from an Ontario nursery, planted Oct. 19; Camino Real, Sabrosa, and Chiflon from a Quebec nursery, planted Oct. 20, 21, and 22, respectively; and Festival and Carmine from a Colorado nursery, planted Oct. 22. Festival produced the highest early season (December) yield (110 g/plant), followed by Carmine (101 g/plant), Chiflon (64 g/plant), Sweet Charlie (52 g/plant), Winter Dawn (27 g/plant), Sabrosa (13 g/plant), and Camino Real (11 g/plant). Part of the reason that Festival and Carmine had the highest early season fruit yields may be due to the fact that these cultivars were obtained from a cool, high light nursery environment that tends to produce transplants that are more vigorous and earlier flowering than the transplants produced in other nursery areas.

Impacts
The 2004-05 GCREC strawberry variety trial provides growers in central Florida the information they need to choose the highest yielding early season cultivars.

Progress 10/01/03 to 09/30/04

Outputs
Eight entries, representing seven cultivars and one advanced selection from the UF/IFAS strawberry breeding program, were evaluated at the University of Florida Gulf Coast Research and Education Center at Dover. Six of the entries were from Ontario nurseries, one was from a Colorado Nursery, and one was from a California nursery. Plants of Festival, FL 97-39, Sweet Charlie, and Carmine were planted on October 15th, while Camarosa, Treasure, Camino Real, and Ventana were planted on October 24th. Festival produced the highest December yield (106 g/plant), followed by Sweet Charlie (49 g/plant), FL 97-39 (35 g/plant), and Carmine (35 g plant). Carmine produced the highest January yield (171 g/plant), followed by Treasure (132 g/plant), Ventana (124 g/plant), and Camarosa (118 g/plant). FL 97-39 produced the highest February yield (242 g/plant), followed by Carmine (168 g/plant) and Treasure (152 g/plant). Carmine produced the highest total (Dec.- Feb.) yield (374 g/plant), followed closely by FL 97-39 (371 g/plant).

Impacts
The 2003-2004 strawberry variety trial at Dover provides growers in central Florida the information they need to choose the highest yielding early-season cultivars.

Progress 10/01/02 to 10/01/03

Outputs
Eleven entries, representing eight cultivars, were evaluated at the University of Florida Gulf Coast Research and Education Center at Dover. Seven of the entries were plants from Ontario nurseries, two were plants from Quebec nurseries, and two were plants from a Colorado nursery. Most of the plants were planted on October 10th, except those of Aromas, which were planted on October 14th, and Camarosa from Ontario, Gaviota, and Treasure, which were planted on October 18th. Camarosa and Festival plants from Colorado produced the highest December yield, followed by Carmine from Quebec and Earlibrite. Average December yield (across cultivars) in this trial was over 70% below that of a similar trial conducted in 2001-02 (127 vs. 37 g/plant). Low December yields, such as those obtained in 2002-03, can be devastating to west central Florida growers, because December is the month in which they, historically, receive their highest returns. For January, Festival from Ontario and Earlibrite were the highest yielding entries, producing around 180 g/plant. Carmine from Ontario came in third with 173 g/plant. These are higher yields than those obtained by these cultivars in 2001-02. Carmine also did well in February, compared to the other cultivars. Carmine from Ontario produced 174 g/plant, while Carmine from Quebec produced 155 g/plant. These yields are similar to the yield obtained by Carmine in 2001-02. Two cultivars, Festival and Carmine, produced over 260 g/plant during the first 13 days in March. And Sweet Charlie came close to that mark, yielding 242 g/plant.

Impacts
The 2002-2003 strawberry variety trial at Dover provides growers in central Florida the information they need to choose the highest yielding early-season cultivars.
